He... Karma is a bitch. From the
UK Daily Mail:
Pictured: The moment a $3million ransom was parachuted to Somali pirates
This is the dramatic moment a ransom of $3million was paid to Somali pirates to end the world's biggest ship hijacking.
The canister full of cash was parachuted onto the Sirius Star - observed by the U.S. Navy who provided these images - and the two-month ordeal of the 25 crew, including two Britons, was finally over.
However things went badly wrong for the pirates soon after the drop - they squabbled over how to split the money and then a wave washed off their getaway boat and drowned five of them.

A bit more:
It is not known what happened to the money or those who survived.
Emphasis mine. I am sure the serial numbers on the bills have been recorded and they will show up in circulation somewhere. I would have loved to see that little scenario play out with them each trying to get "their share" of the money.
